Muting reinvented by Leuze

Leuze Electronic (Germany) – “Smart Process Gating” is the name of a new process from Leuze electronic through which muting processes are made more economical, simpler and safer.

In intralogistics as well as in the automotive and packaging industry, material locks often need to be safeguarded against unauthorized access by means of safety sensors. Previously, muting processes with muting sensors were required in order to clearly identify when transported goods are approaching a protective field and to bridge the passing of these goods through the protective field at the correct moment.

As a result of the SPG (Smart Process Gating) method developed by Leuze electronic, signal-emitting sensors are no longer needed. Based on the MLC safety light curtains, conveyor systems can thus be made more compact. The risk of misalignment or damage to the sensors is eliminated as is the costs for their maintenance and servicing. Furthermore, the purchasing costs, the wiring and risk of manipulation are reduced which increases the availability of the complete safety device.

Particularly in the case of typical intralogistics applications, the height of the protective device is entirely dependent on the safety-related requirements. Synchronization beams do not have to be taken into consideration. With SPG, the first muting signal comes from the process control (PLC), while the second muting signal is generated by the protective field itself. Smart Process Gating requires a detailed knowledge of the process so that the necessary SPS control signals are made available in the expected time window.
